This patch allows user to simply select which GPIOs he wants to use and access them via /dev/gpio_a0 or similar device with standard gpio driver. By default gpio names match pin names printed on the board. So when enabling A3 pin, it will show as /dev/gpio_a3 in runtime. This name can be changed in kconfig. User can also select pin function (input, output, interrupt) as well as standard pin settings like, pull up/down, output type pushpull/open drain etc. All pins that are exposed via boards goldpins are listed in Kconfig. Extra pins that are supported by chiip but are not exposed for easy usage are not listed. To have this nice Kconfig configuration and for things to be easily debugable/understandable it requires code to have big Kconfig and header file with all possible definitions Because of file sizes I decided to split gpio related kconfig and header into separate files. Otherwise it would really make original files hard to read and find anything. Signed-off-by: Michał Łyszczek <michal.lyszczek@bofc.pl> |

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
Contributing
If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
